  • U.S. Patent No. 5,419,028 teaches a method of making a hose coupling. Specifically, a method of forming a ferrule of the hose coupling is taught. The ferrule is then joined to an insert of the hose coupling using well- known methods. These methods include inwardly deforming or crimping the ferrule toward the insert at a horizontal location of the hose coupling different than the horizontal location of an enlarged hex-shaped nut portion. Inherently, separate steps are required to form the hex-shaped nut portion and the joined portion. In addition, because each of the hex portion and the joined portion occupies a separate horizontal space, the ferrule of this method may require additional raw material to construct the coupling. It is therefore desirable to provide a more efficient method of making a hose coupling.
